tomcat servlet runing problem

hi, I have tomcat 4.1.24 installed in my windows 98 SE machine. Tomcat is working fine I have purchased a Book Proffesional JSP second edition. I was trying to run the MyfirstServlet example as described in the book

as written in the book i made the following directories webapps\ch03\WEB-INF\classes\com\wrox\projsp\ch03\myfirstwebapp

wrote the Myfirst.java code inside and it complied fine. but when i tried to run the servler thru the URl as below http://localhost:8080/ch03/servlet/com.wrox.projsp.ch03.myfirstwebapp.Myfirst i get the below message what could be wrong -------------------------------------------------------------------------------- type Status report message /ch03/servlet/com.wrox.projsp.ch03.myfirstwebapp.Myfirst description The requested resource (/ch03/servlet/com.wrox.projsp.ch03.myfirstwebapp.Myfirst) is not available.

That has got to be the most common problem people have with Tomcat 4. When you run a servlet using the /servlet/ nomenclature, it actually goes through something called the "invoker" servlet. There is a nice tutorial on getting Tomcat 4 running here that discusses the invoker servlet. Or search the /conf/web.xml file for "invoker" Bill
